URETHRAL SYRINGE.

SPECIFICATION forming part of Letters Patent No. 488,089, dated December13, 1892.

A Application filed November 18, 1891. Serial No. 412,343. (No modeL) T0aZZ whom it ma concern.-

Be it known that I, EDWARD P. ROCHE, of Bath, in the county of Sagadahocand State of Maine, have invented certain new and useful Improvements inUrethral Syringes, of which the following is a specification, referencebeing had to the accompanying drawings, and to the letters of referencemarked thereon.

The object and nature of my invention will be fully set forth in thefollowing specification and claims.

In the drawings, Figure 1 is a perspective view of my improved urethralsyringe, and Fig. 2 is a sectional view of a part thereof.

Similar letters of reference indicate similar parts in both figures.

A is a short tube or catheter suitably perforated for the passage of theinjection to the urethra. This catheter is connected to a syringe B bythe rublter tube a.

G is a disk or shield attached to the oatheter A and is designed toprotect the hands and instrument from the fluid injection as it returnsfrom the urethra. To the disk 0 and catheter A is attached a springgripping device, (designated as a whole by the letter D.) This grippingdevice is preferably formed of a single piece of wire so bent, shaped,and twisted as to form the middle looped portion d, therearwardly-projecting handles (1' d, and the forwardly-projecting springgripping portions d (1 The looped portion d preferably fits around thecatheter A and rests in a seat or recess 0, formed in the shield O. 7

- The catheter A, shield O, and looped portion dare secured together bysoldering or other equivalent means. The handles 01' d project to therear of the shield G and the gripping portions (1 d extend in front ofthe shield.

In operation when the catheter A is being inserted into the organ thehandles d d are compressed, which permits the gripping portions d d topass over the outer surface of the organ. When the catheter is inposition, the handles 01 d are released and the gripping portions d dwill clasp the organ externally, and thereby hold the instrument inposition. The looped portion cl, being firmly secured tothe disk andcatheter, forms a torsional spring for the handles (1 and grippingportions d Having described my invention, I claim 1. The combination,with a catheter, of a disk or shield and a spring gripping device, thelatter having a middle portion secured to the catheter and shield toform a torsional spring, handles projecting to the rear of the shield,and gripping portions projecting in front of said shield, substantiallyas and for the purposes described.

2. The combination, with a catheter, of a disk or shield on thecatheter, said shield having a seat or recess, and a spring grippingdevice formed of a single piece of Wire bent to form a looped portion tofit around the catheter and rest in the seat in the shield, handlesprojecting to the rear of the looped portion, and gripping portionsprojecting in front of the looped portion, substantially as described.
